Add new flags to skdiff

New flags are:
--nodiffs: don't write out image diffs or index.html, just generate report on stdout
--match: compare files whose filenames contain this substring; if unspecified, compare ALL files
         this flag may be repeated to add more matching substrings
--nomatch: regardless of --match, DO NOT compare files whose filenames contain this substring
           this flag may be repeated to add more forbidden substrings

Also implemented the --threshold flag, which was already documented but not implemented.
